Fiber Optic Interface Modules (OIMs)

Optical Interface Modules (OIMs) connect the EOTec 2000 modem nodes to the fiber optic cable network, and transfer network data between nodes. Cascade different optical modules in a single modem assembly and optically link modems utilizing 850/1300nm optical wavelengths, Multi-mode or Single mode fiber, and SMA or ST* connectors.

A maximum combination of five optical or electrical modules may be connected together in one modem. Inter-module communications and operating power is achieved through the integrated module backplane "BUS" connections of the EOTEC2000 architecture.

Diagnostic Output Feature
2Dxx optical modules provide a full diagnostic output (4-20mA). The output is internally powered and is proportional to the received optical power. The output can be monitored and processed continuously in order to insure the integrity of the fiber optic link. This is beneficial for critical applications such as subsea networking where degradation of the optical signals can be detected before a complete loss of communication occurs. An output less than 4mA indicates loss of optical signal. A pluggable screw terminal connection on the bottom front of the module provides easy access to the output signal.
